Impact assessment of chromite mining on

2008-12-30  Sulfide oxidizing bacteria play an important role in the formation of Acid Mine Drainage (AMD),, and these can be control by wetlands, while waste rock and tailings are the most significant sources of acid drainage, other mine components such as open pit surfaces, underground workings, stockpiles and concentrate stage and loading areas are also potential sources of AMD.

Acid mine drainage from coal mining in the United

2020-9-1  Acid mine drainage (AMD) continues to be a concern in coal mining because it reduces surface water and groundwater quality (Verburg et al., 2009) and may perhaps persist for several years. In the U.S. only, AMD pollutes over 20,000 km of streams (Skousen et al., 2019).

Acid mine drainage arising from gold mining activity

2003-3-1  This study revealed that the ground water within the mining district is heavily contaminated and acidified as a result of oxidation of pyrite (FeS 2) contained within mine tailings dumps, and has elevated concentrations of heavy metals. Where the water table is close to surface, the upper 20 cm of soil profiles are severely contaminated by heavy metals due to capillary rise and evaporation of the ground water.

Chromite mining pollution, environmental impact,

2020-9-24  Chromite mining activities are indispensable for production of goods and services. Sukinda is a major mining site of Odisha, India, polluted by chromium, which is highly toxic in its hexavalent form. The Sukinda valley is a rich source of chromites, amounting to almost 95% of Cr available in India, and is the fourth most polluted site worldwide.
